iotdb logs to console by default

[mcarlson]

Whenever I use iotdb, I see objects logged to the console. This is useful for debugging, but it would be nice to be able to turn it off. Is there a way to do this now?

Try (new function) _.logger.silent(). Blog post https://iotdb.org/social/imadeit/post/142404844631/changes-to-iotdb-logging
